gave these as a gift to my corvette enthusiast brother. he said 'thank you. It's good. I lost one of my caps so I can use it. Oh, those are Corvette caps. That's cool. Thank you.' These statements correspond to the fact that the average person loves them - he is as stoic as our father. that was almost 3 months ago. he hasn't said anything else about them, so it's safe to say they work well, ie. H. Fit, don't interfere with the sensor, keep the finish, etc. If there are any issues I'll update this review.
